CT Colonography

Screening performance on adenoma and advanced neoplasia detection is consistent among radiologists using metrics that included advanced neoplasia detection rate and per-polyp endoscopic confirmation rate.

A new modeling study has found that people who undergo colonoscopy at age 50 years in which no precancerous polyps are found can be rescreened at age 60 years with one of three alternative methods, rather than undergoing colonoscopy every 10 years.

Costs of computed tomography colonography (CTC) discourage patients who have previously refused colorectal cancer screening, according to a study published in the American Journal of Roentgenology (2010 Aug;195(2):393-7).
